I did some reading because I've never really been happy with my roasted seeds in the past -- it's been more of a fun thing to do than something that produces an actually tasty treat. And having tried it, I think it's the boiling. I boiled for ten then roasted for ten. I started letting them cool, but found that they were still soaked from the boil. So I put them back in the oven for another ten, checked them for doneness and gave them another five. I'm no expert yet, but they turned out pretty great.
